DIE-CUTTER MEANS.

Application led January 11, 1924. Serial No. 685,605.

The object of the invention is toprovide an expeditious cutter die means for accurately forming such parts.

Objects pertaining to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices andmeans described in the following specification. The invention is clearly defined and ointed out in the claims.

A structure whic isa preferred `embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is an elevation view of the cutter die means with the stripper plate means, shown by dotted lines, in place. V y Fig. II is an inverted plan view of the parts appearing in Fig. I.

Fig. III is adetail view of the stripper plate on itsfsupporting guide rods.

Fig. IV is a detail view in miniature of the anvil or work supporting block on which the work is placed to be cut.

In the drawing similar reference characters refer to similar parts throughout the several .views The parts will be referred to by numbers.

1 is the supporting headv for the cutter plates, which conforms to the shape of the carpet sweeper case end that is tobe die punched. Guides 2 and 3 are at the front and rear for guiding engagement of the top and bottom of the blank, and side guides 4; and 5 are provided for engaging the ends of the blank. Straight cutter knives, beveled and oblique on their outer surfaces, are secured to the head 1. Knives 6 and 7 are each side of the guide 3 to trim .off the bottom ed e of the end, and knives 8 and 9 of precise y similar construction are on the beveled portions at the upper side at each end. These knives and other parts co-operate with the anvil or work support 10 (see Fig. IV).

Within and supported on the face of the supporting head 1 are punches 14, 14 for the pivot supports at each side of the end portion, and a punch 15 for the axle of the brush. A stripper plate 11 is within the knives and guides and is reciprocated by the rods 12 connectedby the cross hea-d 13 at the upper end.

This structure can be considerably varied and the relation of the parts varied to make box ends and for similar purposes. I desire to claim the same specifically and broadly, `as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a punch structure for making box ends, the combination of a suitable knife carrier head, guides at the front and rear and at each side thereof for engaging the blank, beveled angular shearing knives disposed upon said head to trim the top and bottom obliquely, an anvil-like work support conformed to co-operate with said knives, a series of punches on said head for forming holes in the said blank, a stripper plate conformed to the space between the knives and perforated to accommodate the punches, and suitable guide rods for carrying the same, with a cross head for its actuation.

2. In a punch structure for making box ends, the combination of a suitable knife carrier head, guides at the front and rear andl at each side thereof for engaging the blank, beveled angular'shearing knives disposed upon said head to trim the top and bottom obliquely, an anvil-like work support conformed to co-operate with said knives, and a series of punches on said head for forming holes in the said blank.

3. In a punch structure for making box ends, the combination of a suitable knifecarrier head, guides at the front and rear and at each side thereof for engaging the blank, beveled angular shearing knives disposed upon said head to trim the top and bottom obliquely, and an anvil-like work support conformed to co-operate with said knives.

In Vwitness whereof, I have hereunto set my hand.
